A crisp salad with the fresh flavors of chilled gazpacho is a perfect starter for any meal. For this version, the salad ingredients are layered in a jar and refrigerated. You can make one large jar of salad or prepare individual servings — perfect for outdoor dining.
Layer half of lettuce, pepper, cucumber, tomato, celery and onions in a narrow 2-quart glass jar with lid. Repeat layers with remaining vegetables. You can also make individual servings in smaller jars.
Combine remaining ingredients in a glass jar with lid; cover and shake vigorously. Pour over vegetables. Cover and chill at least 4 hours, turning container occasionally.
